VEHICLE DISCHARGING FROM THE BOTTOM.

T 0 all whom it may concern:

Be it known that I FRrrz FINCKH, residing at Essen-on-theuhr, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Vehicles Discharging from the Bottom, (for which I have filed'an application in Germany September 12, 1919,) of which thefollowing is a specification. V

This invention relates tovehicles discharging from the bottom having two bottom doors opening automatically under the action ofthe weight of the load and having movable side walls .which come into sliding contact withuthe bottom doors, on the discharging movement of the parts, one of said side walls at least being held, when in the loading position, by'means of an abutment,

at a distance from the corresponding bottom trap, sothat on the-discharging movement only, said sliding contact closed by force is established between the bottom doorand the corresponding side wall. The object of the present invention is to so improve self-dischargingvehicles of this kind that the walls of the vehicle, which are to be displaced by the bottom doors on the discharging operation, execute, at'the beginning of this operation, an additional movement in order to loosen the load, which often tends to be: jammed.

.One embodiment of the subject matter of the invention is illustrated by way of example in the accompanying; drawing in which Fig. 1 shows aisection of the self-discharging vehicle ready to be loaded, and

Fig. 2 a similar section of the wagon after the discharging operation has been completed.

On the sills a of the under frame Aof the vehicle which has fixed end walls A there are swingingly mounted the two bottom doors B. hen in the loading position, these bottom doors are inclined towards the middle line of the vehicle and bear against each other with their lower edges in a hopper-like manner.

The side walls C of the vehicle are swingingly suspended at their upper edges from the end walls A and bear, in the loading position of the parts, against movable abutments D rotatably mounted on side shafts D The shafts D in their turn, are mounted on the end walls A Specification of Letters Patent.

- The abutments D are on levers D? which are connected to one arm F of bell-crank 1evers F F through the intermediary of rods E. ,Theotherarms, F of said bell-crank levers are fixed on a side shaft F? mounted on the frame A of the vehicle and'are con; nected, by means of rods G, to the lower part of the corresponding bottomdoor B. The length of the rods G and of the lever arms F} are so chosen that in the loading position of the'vehicle, the joints of these parts lie in a straight line, so that-the systems of rods G F assume a dead'centerposition and then prevent the bottom doors B from being opened unintentionally. On each of the ends of the side shafts F proj ecting beyond the end walls A thereis fixed a lever F 3 which is connected, by'means of arod H, to a lever J, The levers J are rigidly place or locked withrespect to its end wall.

meansof the abutments D the side walls C of the vehicle are held, when in the loading position (Fig. 1) ,in such a manner that 1 a space: exists between their lower edges and theupper edges of the bottom doors B.; Y.

The abutments D are so formed that their faces abutting on the side walls assume their position nearest the middle line of the vehi cle when the parts are in the loading position. r

In order to prepare the discharging movement of the described parts, the hand lever L is freed by releasing it from the clip or look M and then turned in the direction of the arrow m- (Fig.1). In consequence of the described arrangement of the system K J H F at the same time the side shafts F turn in the direction ofthe arrows 1 (Fig. 1). The rotationof the shafts F is taken part in also by th bell-crank levers F F On their rotation these latter draw with them the adjacent rods so that the rods G F are swung out of their dead center position and the bottom traps then drop down under the ac- Beside these-levers J, the shafts.
